So I found a deal on a Samsung 1tb 7200rmp hard drive for $25, but it has 32mb cache and not 64. Will that be an issue and will there be a significant speed difference?
It sort of works like the RAM on your computer, the more the better. In this case, there is somewhat of a significant difference when buying 32 and not 64. Guess the real question comes down to how fast do you need to access that HD? or if you are just going to be using it just as a back up, then you should do just fine.
